Allsun EM555 Electric Fence Tester | Fault Finder & Digital Voltage Meter Up to 9.9 kV

Meet the Allsun EM555 Electric Fence Tester

Designed for fence owners, hobby farms, ranches, and property managers, the Allsun EM555 is a compact blue handheld device that blends digital voltage monitoring with practical fault-finding. Its clear display and intelligent sensing help you understand how your fence is performing without guesswork, making routine checks more predictable and less stressful.

What it does

The EM555 provides a reliable readout of fence voltage across a broad range. With a sensing wire length of 57 inches, it can reach along typical fence lines to offer a quick snapshot of energization. The device is built to support on-site checks where you need fast, actionable information rather than wait for remote readings.

Key benefits at a glance

• Voltage measurement range from 0.3 kV to 9.9 kV, with a 57-inch sensing wire for better reach along fences.
• Clear LCD readout that updates with live pulses, helping you interpret results at a glance.
• Power-saving design that wakes on pulse and powers down after about 4 seconds of no pulse.

• Test voltage along fence lines and through fence controllers to verify energization and performance.
• Keep it on hand for routine maintenance and fault finding, reducing guesswork during inspections.
• Compact, portable tool you can carry during gate checks, livestock movements, or remote fence checks.

Real-world use often involves walking along long perimeter setups, checking around gates and corners, and confirming that the energization aligns with expected levels. The EM555 is designed to deliver clear, numerical feedback in those moments, helping you plan maintenance or adjustments with greater confidence. This device is intended for fence monitoring and fault detection, not as medical equipment, and results can vary with environment, circuit design, and pulse characteristics.
